The number alone is not enough. You also need to know what the number is measuring.
Grams and ounces describe how much something weighs. This is often the most repeatable way to measure ingredients when precision matters.
Cups, tablespoons, teaspoons and millilitres describe the space something occupies. Different ingredients can fill the same volume while weighing very different amounts.
Celsius, Fahrenheit, fan settings and gas marks describe cooking heat rather than ingredient quantity. Oven type and calibration can still influence the real cooking conditions.
Ingredient Density
Equal volume does not mean equal weight.
Flour, sugar, cocoa, oats, butter, oil and honey all occupy space differently. That is why there is no universal “one cup = one gram value” that works for every ingredient.
